HANGER. FOB ELECTRIC LIGHTS.

To all whom it may concern:

Be it known that I, EDMUND H. WEBER, a citizen of the United States, anda resident of Chisholm, in the county of St. Louis and State ofMinnesota, have invented an Improved Hanger for Electric Lights, ofwhich the following is a specification.

My invention is a hanger intended as a substitute for the so-calledcrow-foothanger and various others now in use. It is distinguishedchiefly by a spring-support and rocking bearing for the hanger proper.

The construction is extremely simple and inexpensive and the device maybe easily and quickly attached to and removed from the ceiling or otheroverhead support.

The details of construction and operation of the invention are ashereinafter described, and shown in the accompanying drawing, in which-Figure 1 is a side View illustrating the invention as applied in use.Fig. 2 is a horizontal cross-section on the line 2-2 of Fig. 1. Fig. 8is a perspective view of the stirrup constituting the hanger proper.Fig. 4 is a side and sectional view illustrating a means for attachingthe hanger to the ceiling in a conduit system.

I will first describe the invention as illustrated in Figs. 1-3. Theseveral parts constituting the hanger are attached to a support by awood screw 1, which is inserted vertically in the ceiling where it isdesired to suspend the lamp or light fixture. The stirrup 2,constituting the hanger proper, has approximately the form of aninverted U, and the head as of the lamp or lamp fixture is pivoted by acotter-pin 3 between the free ends of the stirrup. The head or centralbow portion of the stirrup 2 is provided with an opening 4 that receivesa tube 5 through which the screw 1 passes. This tube is made ofinsulating material and has a flanged base or washer 6 of similarmaterial. A corresponding washer 7 is applied between the tube and theceiling. An iron washer 7 rests on the head of the screw, and theinsulating washer 6 lies in direct contact with it. A helical or spiralspring 8 loosely encircles the tube 5 and rests upon the insulatingwasher 6. The apertured head of the stirrup 2 which receives the tube 5rests directly upon the spring, and is provided with downward bends 2,as indicated in Figs. 1-3, which constitute points of bearing that arethe only portions of the stirrup in contact Specification of LettersPatent.

with the upper convolution of the spring.

The size of the opening 4 in the stirrup being I considerably greaterthan the diameter of the tube 5, as indicated in Fig. 2, theconstruction of the stirrup with the downward bends 2 obviously enablesthe stirrup to rock or swing laterally in any vertical plane.

In Fig. 4 I illustrate the hanger as a whole attached to a threadedpiece 9 which is adapted to fit a fixture stud in the outletbox in aconduit system. In other words, such piece 9 is provided with anenlarged threaded opening in its upper end and with a smaller threadedopening in its lower end which receives the metal screw l In all otherparticulars the construction, arrangement, and operation are the same asillustrated in Fig. 1.

It will be seen that the main advantage of this hanger independent ofits extreme simplicity and adaptation for easy attachment anddetachment, is the adaptability of the stirrup or hanger proper to hangplumb whether the attaching screw be Vertical or not, so that the lampfixture is always suspended in the desired position. The fixture m beingsupported on the cotter-pin 3, does not require to be turned in hangingso that fixture wires are not abraded. Furthermore, the attachment tothe lamp may be effected with great ease and rapidity.

The spring 8 may be made in difierent sizes according to the weight offixtures to be suspended, and in allcases absorbs jar or concussion sothat the life of delicate lamps, such as the tungsten, is considerablyprolonged. It is further apparent that the form of the attachment issuch as to prevent injury by lateral vibration. The stirrup and springare insulated from the supporting screw, and the fixture is thusentirely insulated from the ceiling. The size of the hanger as a wholeenables an ordinary canopy to easily cover it. The stirrup may becheaply constructed of sheet metal, say steel, and may be stamped up.All the other parts except piece 9 are stock articles, or may be easilyformed of stock material.

What I claim is:

1. The hanger for the purpose specified, comprising an approximatelyinverted-U- shaped stirrup, a supporting screw, an insulating bodyarranged between the screw and stirrup, and a spring upon which thestirruprests, substantially as described.

2. The improved hanger comprising a de V vice for attachingit to asuitable support, I 1 an insulating member applied to such device,

a spring applied to the insulating member,

and an inverted U-shaped stirrup constituting the hanger proper, thesamebearing upon'tthe spring, and provided at its lower I end with means forattaching it to a lamp fiXture,-substantial1y as described.

8. In a hanger of the classindicatd,-the combination with a support andan insulating member 'appliedthereto, of a spring encircling suchmember, and an inverted U- I shaped stirrup having its upper endprovided with an opening 'of considerablygreater diameter than theinsulating member, the

stirrupresting directly upon the spring, substantially as described. 7

4. In a hanger of the class indicated, the support and an insulatingmember 'applie thereto and suspended by it, of ahelical springsurrounding such member, and an inverted U-shaped stirrup constitutingthe hanger proper and provided init's central'upper' portion with anopening for receiving said member and with downward bends constitutlngbearings that rest in direct contact with the spring and for the purposespecified.

5. In a hanger of the class indicated, the combination with a screwconstituting a ceiling attachment and insulating tube, an insulatingwasher applied thereto, a helical spring surrounding said tube andresting upon an insulating base, and an inverted U-shaped stirrupconstituting the hanger proper and resting upon'the same, substantiallyas described.

6. In a hanger of the class indicated, the

combination with a ceiling support and an insulating member appliedthereto, of a spring applied to said member, and an inverted U-shapedstirrup constituting the hanger proper and resting upon the spring,substantially as described. I
